MoTeC Introduction 1
Introduction
The PWC Plug-In ECUs are direct replacements for factory ECUs on a select
number of popular PWC models. They are based around the M400 Marine
ECU.
Note: ECUs (Engine Control Units) are often referred to as Ignition Systems.
Complete with a wiring loom and mounting brackets, PWC Plug-Ins are
convenient and cost effective to install because they eliminate the need to
rewire the PWC. They simply plug into the factory wiring harness using the
original sensors, fuel system and factory dash.
Features
The M400 Marine ECU comes with a range of features as standard and
several options available as upgrades to customise and grow your system.
These additional features are activated through a simple password acquired
from MoTeC, at any time when you need it. See Upgrades.
Engine Tuning Features
• Windows based ECU Manager tuning software with user definable screen
layouts.
• Individual cylinder tuning of both fuel delivery and ignition timing.
• Selectable channels for table axes.
• Fully configurable axis points on all tables.
• Free access to wideband Lambda and data logging for initial tuning.
Available for the first 8 hours engine running time.
• Possibility to communicate directly with OEM dash.
• Suitable for engines requiring the latest complex control functions, such
as drive by wire throttle control.
• Capable of all other modern control functions, such as:
o Launch control
o Overrun boost enhancement (anti-lag)
o Boost control
o Nitrous injection
• Fully configurable sensor inputs including custom calibrations.
• Configurable receiving and transmitting data via the CAN bus.
• Capable of receiving data from multiple Lambda measurement devices
via CAN.

MoTeC Kawasaki Installation 13
MoTeC ECUs control the idle stepper motor without reference to its initial
position when the Jet Ski is powered up. The stepper may still be parked in
the open position upon the first start , resulting in high idle RPM.
There are two strategies which reduce this condition:
1 – Preset the idle stepper before removing the stock ECU.
As the stock ECU repositions the idle stepper to a parked position when
stopped, it can help if the idle stepper motor is unplugged before the Key is
removed. To do this the engine should be running in the water at a stable idle
speed, with the engine at normal operating temperature. Unplug the stepper
motor plug which is located on the throttle body, and then remove the Key.
With the stepper in its normal operating position the PWC Plug-In ECU can
now be installed, and the stepper motor plugged in prior to running the
engine. This procedure need only be followed once, as the M400 ECU does
not park the stepper motor when the key is removed.
2 – Make temporary changes to the idle control settings to
close the idle stepper.
After initial installation of the Plug-in Adaptor Loom it may be necessary to
make temporary changes to the idle control settings until stable conditions are
achieved. The best option for a new installation is to make the stepper close a
little each time the engine is started.Then the standard idle control settings
may be re-set for further use.
• In Functions | Idle Control | Setup, set the ‘Activate RPM’ to 5000.
• In Functions | Idle Control | Initial Position, set all values to -50.
If you have -50 set for the initial position and after about 6 starts the engine is
still idling fast, the answer may be the idle air bypass in the throttle body (very
difficult to adjust).
Once a good starting idle has been achieved, re-set the control values:
• In Functions | Idle Control | Setup, set the ‘Activate RPM’ to 2400.
• In Functions | Idle Control | Initial Position, set all values to 0.

Remove the factory ECU (three T25 Torx screws) and presupplied mounting plate before the M400 ECU is fitted:
• Screw 4 supplied M6 Stainless nuts on the studs
protruding from the top of the mounting plate.
These serve as captive spacers. (see right)
• Invert the plate and ensure that the 3
rubber rings are seated on the rubber
bushes which are fed from the top side
of the plate. (see picture at right)
• Place the plate with rubber inserts
over the plastic mounting bracket
on the PWC.
• Firmly screw 2 x 6mm cap screws
with washers in the lower 2
positions, and 1 x countersunk
screw without washer in the central
position. Do not over tighten.
• Ensure that the rubber mat with
hole is mounted over the centre
countersunk screw.
• Fit the waterproof relay to the top right screw post
which protrudes from the mounting plate.
• Fit the M400 ECU and place the 2 stainless steel
brackets onto the 4 screw posts, after first fitting
the rubber trim strips to the underside of the
brackets.
• Secure the brackets (and relay) with 4 x M6
washers and 4 x M6 Nylock nuts.
